SPECIFICATION forming part of Letters Patent No. 306,623, dated October 14,1884.

Application filed June 28, 1884.

T (6 whom it may concern: I

Be it known that 1, JAMES N. JOHNSON, a citizen of the United States, residing at Buffalo, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains. to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification;

Figure 1 of the drawings is a vertical sectional view of my device. Fig. 2 is a plan view of the same, and Fig. 3 is a front view.

The invention belongs to that class of agricultural implements used to heap the soil around the shoots of sprouting or growing corn, cotton, or other crops planted in rows.

. Such implements are frequently called hillers, but are, properly, cultivators.

The object of the invention is to cultivate or hill two adjacent rows simultaneously, or while the machine is driven in one direction; and it consists, essentially, in fixing to a transverse shaft having bearings in the frame of the machine a cam roller and a pulley, the former rotated by one of the wheels by means of any proper connecting mechanism, and the latter actuating a lever which vibrates a depending arm, on the lower end of which the i proper cultivator-points are attached.

In the accompanying drawings, A is the tongue of the machine, bolted to the transverse beam 13, from the ends of which extend vertically downward the equal and similar arms, b and b, furnished at their lower ends with the transverse bearings b and If, respectively.

The axle of the wheel 0 journals in the bearing b ,and the axle of the opposite and equal wheel, O, journals in the bearing b, having upon it the pulley, or, if necessary, the sprocket-wheel 0 between said wheel and hearing. The arms I) b and wheels 0 O are situated at equal distances from the tongue, on each side of the same.

D D are equal and similar parallel arms, extending backward from the widened rear end of the tongue, and provided at their rear (No model.)

f is a pulley, or, if necessary, a sprocketwheel, fixed to the end of the shaft H, projeeting outward from the bearing (2.

G is a band connecting the pulleys c and f, by which motion is communicated from the former to the latter, and the shaft revolves when the wheel 0 is in rotation, (t. 6., when the machine is moving.) WVhen c and f are sprocket-wheels, holes 9 9 have to be made in the band to accommodate the pins on the same; or a chain may be substituted for the band.

H is a horizontal rod journaled longitudinally in a proper bearing fixed centrally to the lower surface of the beam 13.

h is an arm extending vertically upward from the rear end of said rod, behind the beam B, and havingv on its upper end a pin, h; to enter the groove f of the cam-roller, which groove is so formed as to vibrate the arm when the cam-roller revolves.

h is an arm extending vertically downward from the front end of the rod H, in front of the beam B, and provided with the longitudt nal slot h" near its lower end.

If is a bar having attached on each side of its lower end proper cultivator points, h h and attached to the arm h by means of a setscrew passing through the slot h". The said slot and screw render the bar 'h both laterally and longitudinally adjustable on the arm if.

The operation of the machine is as follows: \Vhen the machine moves forward, the tongue being between two adjacent rows, the rotation of the wheel 0 revolves the cam roller by means of the pulleys or sprocket-wheels and connecting band or chain, and the cam-roller, by means of its groove and arm 72/, vibrates the arm if from side to side, and causes the cultivator-points attached to the lower end of the latter to act successive] y toward the rows on both sides.

shaft II, carrying a eranlrarln, as shown 10 engage a earn-groove in the shalt ll, the arm h having its lower end vertieall y slotted, and the arm 7L",(30lll100l16(1f011110 said arm if, and means, substantially as specified, for operating the same, as set forth.

In testimony whereof I aflix my signature in presence 01 two witnesses.

JAMES N. JOHNSON.
